		char *	id,
		int	device,
		struct snd_hwdep **	rhwdep
	)

snd_hwdep_new - create a new hwdep instance : the card instance : the id string : the device index (zero-based) : the pointer to store the new hwdep instance

Creates a new hwdep instance with the given index on the card. The callbacks (hwdep->ops) must be set on the returned instance after this call manually by the caller.

Returns zero if successful, or a negative error code on failure.
